ORSON ll. WOODVORTH, OF INDIANAPOLIS, INDIANA.

CHRONOSPHYGMOMETER.

SPECIFICATION forming part of Letters Patent No. 576,180, dated February 2, 1897.

Application filed April 10, 1896.

To all whom {it may concern:

Beit known that I, ()RSON I-I. WooDwoRrH, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Ohronosphygmometers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improved devices and mechanism for timing and enumerating the movements of the human pulse or the' beats or pulsations of any pulsatory body.

A leading characteristic of this invention is its effective adaptation to practical use in connected attachment to and combination with the running and timing movements of a watch of the size, character, and construction usually carried by practicing physicians and surgeons. V

The general objects and nature of my invention are set forth in this specification and accompanying drawings, in which similar letters and figures of reference indicate corresponding parts throughout the several views.

In the drawings,'Figure 1 is a general plan view of the operative parts of the invention shown in connection and combination with portions of the running movements of a watch. Fig. 2 is an enlarged representation of the acicula or pulse-timing needle and the various devices directly employed to actuate said acicula, Fig. 3 shows a central sectional view on line a: y of the watch and especially its upper plate C and inner case or cap B as they are employed in combination with the acicula; and Fig. 4: represents the watch with the acicula tube L extending outwardly through aperture N in cap B and the point of the acicula K K slightly protruding from the outer end of said tube.

My improved chronosphygmometer is especially designed and adapted for the use and convenience of physicians and surgeons in taking their patients circulation, which object by the use of this invention they are enabled to readily and correctly accomplish Serial No. 587,048. (No model.)

' entirely by their sense of feeling and without being required to employ their sense of sight or hearing. Thus by the use of my improved instrument any patients circulation can be taken in the dark more conveniently and ac curately than it can be done by daylight or any artificial light under the ordinary method heretofore employed.

Referring in detail to the drawings, A is the outer case of the watch. B is the ordinary inner cap of said case.

0 is the upper, and D the lower plate, between and by which the running movements of the watch are held in position.

D is the dial, and D the glass or crystal.

E is the center wheel, F the third wheel, and G the second wheel of the watch.

II represents an annular disk or auxiliary wheel attached to and carried by third wheel F, said disk being riveted or otherwise securely fastened to said third wheel, as at 13. Said disk is provided with actuating-studs J J, formed integrally therewith or attached thereto and adapted to engage with and act uate arm K of the lever K, pivoted in eyes 6, secured on the plate 0, and thus impart motion to arm K and through it also actuate the pulse-timing needle K K, carried thereon and extending outward through acicula-tube L.

S is the acicula-spring, firmly attached to spring setting arm 9, which is jointed to setting-block M, said spring 8 constantly bearing upward on arm K carrying the acicula K K. Stud 11 is firmly aiiiXed to block M and adapted to receive set-screw 12 to regulate the pressure of spring 8 on arm K Actuating-studs J J are so formed as to extend upward at right angles from the outer edge of the upper face of the disk H as far as desired, and are then deflected at right angles and extend outward parallel with the direction of the cogs of wheel F and toward the periphery of said wheel as far as practicable without interfering with the pinion 16 of the second wheel G. Just enough actuating-studs are provided on disk H to cause one upward and outward thrust of the acicula or needle K K each half-minute by means of the successive engagements of said studs with arm K as wheel F and disk H conjointly revolve with the ordinary running of the watch.

The practical operation of my improved cl1ronosphygmometer is substantially as fol.- lows: The watch to which and with which my invention is attached and combined being wound up, running, and keeping time, the wheel F rotates as per arrow (1., and the actuati rig-studs .l J of disk ll, attached to and carried by said wheel, successively engage with arm K by means o't' con nccting-rod l(,which is jointed to upper plate 0 by suitable joints or eyes c c and may be ol any desired length and size to suit its location and ccmnection with arms It and it. Arm li extends downward from its right-angled junction with rod 1: to its successive operalde engagements with said studs J .I. At; each of said engagen'ients a stud .l' of disk ll presses arm K aside, slightly rotates connecting-rod K in joints or eyes 0 c, depresses armv it. to dotted lines 15, and thereby witlulraws the acicula downward in its tn be L, and these movements of the parts mentioned are continued until the actuatingstud then pressing againstthe lower part of arm K passes beyond said arms extreme lower point, whereupon the constant upward pressure of acicula-spring 8 in notch '7 on the under side of arm hi instantly stops and re verses the motion olf arm K and forces it immediately back to its former position at the dotted lines ll, and arm ii is also simultaneously forced upward against the under side of plate U from its former position at the dotted lines 15, and at the same moment the acicula K K, carried by said arm, is by said pressure thrust upward through its tube L, with its extreme point; slightly n-ojecting outward through said tube. This extreme point of the aeicula is made sulticiently sharp so that when it is thrust upward and outward through tube L in the manner described and under a normal pressure of the acicula-spring 8 said point will slightly penetrate a linger or thumb gently pressed over the outer open end of tube L, which extends outwardly through the aperture N in cap 13 and llush with the outer surface of said cap.

It is evident that it the pressure of aciculaspring 8 in notch 7 of arm K. is too strong it will retard the tree running of the watch and it said pressure is too weak the outward thrusts of the acieula-ptnnt will not sufficiently penetrate the thumb or linger ot the practitioner when using the ehrtmosphygmometer in taking a patients circulation. 'lheretore to most etli'eclively regulate the pressure of said spring the setting-block M is attached to or inserted in the upper plate (7 of the watch, the spring-setting arm fl is jointed at 10 to said bloclc, stud it is rigidly al'lixed thereto, and set-screw 12 is titted to operate in and through said stud and againstarm 9, which has one end of the acieula-s1in'ing attached lirmly thereto, as shown. With the seven elements last lllOlll.l()llOtl-\l7.., the block 11:, plate 0, swing-setting arm 9, stud 11, set-screw 12, and the aeieula-spring S all arranged and attached as indicated it is plainly apparent; that screwing set screw 12 inward against spring-sctt-ing arm 5) will el' lectivelyincrease the pressure ot' spring 3 on arm K and screwing said set-serew on tward will etlcctively decrease said pressure, as may be desired.

in the practical. use olf my improved chronosphyginometer the physician or surgeon takes inv his hand the combined instrument, which outwardly resembles an ordinarywatch, and holding it in any convenient manner so that a thumb or linger gently presses on the cap l3 over the outer end ol. tube l.- and the acicula-point therein he will soon l'eel. the light thr sis of the acicula-point repeated every half-minute with the utmost regularity. Then to take a patients circulation he has only to hold the instrument as above indicated, apply to the patients pulse the lingers ol the same hand with whichhe holds the in strumentor those of the other hand, and con nt the pulsations from the instant he feels a thrust of the aciculapoint until he feels the next thrust or as many more as desired, the tlnrusts occurring precisely one-half minute apart or at the uniform rate ot exactly two thrusts per minute. 3y thus using the invention the pulsations may be readily and accuratelytimed and enumerated in the dark, even it' the practitioner should, un'lforl w natcly, become entirely deaf and blind.

The actuating-studs .l 1 maybe inserted in the upper surfaces of wheels 1 when said wheels are being manufactured, but I prel'er to attach to said wheel the disks ll, with their act;uating-stmds already 'l'ormed thereon, because such disks can readily be so attached after the watches to which said wheels belong have been riuming'several years, and. when so attached the other changes required in the plate, cap, or other parts of the watch can then be made, and thus a watch and the distinctive features of this invention may be combined and unilied after the watch has been used several years or when the combimn'l chronosphygmometer is beingmanufactured, as may be desired. Plate (1 shown largely cut away to exhibit operative parts of the invention, and plate ID and cap l; are thus cut away for the same purpose.

Arm K rod. K, arm K", and the acicula h' K are all continuously (jaonnecled in one entire piece at the right angles 3 5 and. the lengths of the parts named between the angles 53 and '-l and eland 5 depend on the dimensions of the watch lo which they are applied.
